    Hello, I’ve been having an HDMI-CEC problem for months now. My TV is a Samsung UE40D5700RS and I use the Z11 Pro Max as my set-top box. A few weeks ago, the HDMI-CEC function was still enabled on both the TV and the Z11 Pro Max, but as I’ve been experiencing the problem more frequently where my TV kept switching on and off constantly – presumably because it was receiving an incorrect signal from the Z11 Pro Max – I’ve just disabled it permanently. I followed these steps to clear the HDMI cache on the TV: 1. Disconnected the HDMI cable from both devices. 2. Unplugged both devices from the mains. 3. Waited for 2 hours. Unfortunately, the problem still persists and I’ve really had enough of it. Yesterday, the TV didn’t switch itself on and off whilst I was watching it. And today it’s causing problems again. Is there a bug in the HDMI-CEC function on the Z11 Pro Max that keeps sending the wrong signal to the TV?

    Hi,

    do you use original hdmi cable from the box?

    No, a ‘Silvercrest’ brand HDMI cable. The problem persisted even after changing the HDMI cable and the HDMI port. Something happened just now that had never happened before. This time, the TV simply switched off completely. After switching the TV back on, the problem with it constantly switching on and off started again.

    Not sure and its just guess, it could be also your TV and bad handshake, like i told just a guess. You can try to do factory reset, setup fresh again and see if the issue goes away.
